Iris Segmentation Code Matlab

这是matlab版的视频水印，仅供初学者参考。(This is videowatermark code.)

Matlab绘图系列之高级绘图，可以画特殊的图像(Matlab Mapping Series High drawings, special images can be painted)

说明：  一种基于混合策略的改进粒子群优化算法，包括执行程序hpso.m和参数设定hPSOoptions.m两个源文件。代码清晰，易于改进实现。结果显示有效的提高了SPSO的性能(A hybrid strategy based on improved particle swarm optimization algorithm, including the implementation of procedures and parameters set hpso.m two hPSOoptions.m source file. Code clear and easy to improve the achievement. The results showed that the improvement of effective performance of the SPSO)

用matlab实现的主元分析算法，很实用的程序，经调试通过(Matlab principal component analysis algorithm, very practical program, the debugging through)

灰度图转换，可以把彩色图片转换为灰度图片。并进行计算(Grayscale conversion, color images can be converted to gray-scale image. And calculated)

说明：  基于稀疏表示的算法，对Donoho提出的Cartoon image进行纹理综合(Algorithm based on sparse representation of Donoho proposed Cartoon image texture synthesis)

在MATLAB下对LDPC的编译码。比较基础，用以理解。(In the encoding and decoding of the LDPC MATLAB. Basis of comparison for understanding.)
